Artworks

Jatiwangi art factory

"JaF is a community that aims to draw attention to the historical roots of Jatiwangi as a center of brickmaking and formerly the largest roof tile industry in Indonesia, and to form a collective awareness and identity for this region through art and cultural activities. The aim of these artistic projects is to achieve a greater awareness of and thus a more appreciative approach to the material clay."

Kimchi and chips, Another moon

"Another Moon is a large-scale outdoor apparition that creates a technically sublime second moon in the sky. As the original moon is visible as a reflection of sunlight in the sky, this second moon is created by a cross-temporal reflection of sunlight gathered during the day, projected back into the sky at night.

Experiments

Joule thief

"The joule thief circuit massages the voltage and current coming from the battery so that the voltage is high enough, for periods of time, for the device to work continuously."

Karl Heinz Jeron, Fresh Music For Rotten Vegetables

The Workshop and participatory installation with DIY audio devices Fresh Music For Rotten Vegetables by Karl Heinz Jeron is about generating sounds from vegetables and fruits that are already unsellable in supermarkets for optical reasons. In the description of the project, the author wrote: The electronic devices built by the participants are controlled and fed by current generated by use of the collected vegetables. According to the state of the vegetables, the sound, the colour of the sound, and the volume of the sound are varied. Thus, an improvised piece of music is created from the most simple parts, and a garnish.

Background

The project is a direct reference to a “lemon battery,” that is, a battery built from lemons. Interesting in this project is the sound generated that varies as vegetables and fruits change state over time.

The simplest interaction between organic and non-organic elements could be demonstrated with a lemon battery, which generates electricity from a chemical reaction between acids and two electrodes of different metals – zinc and copper. Placed within one small or several normal-sized lemons, the setup is identical to Volta's electrical battery. In the lemon battery, the copper serves as the positive electrode, while a piece of zinc acts as the negative electrode. Citric acid triggers the chemical reaction between the negative and positive electrodes, generating a small potential difference, which, in turn, becomes the electrical current. The electric current could also be produced by, for example, potatoes, or humans.
